firewire and kernel 2.6.7
Hello group,
I have an external firewire (SBP-2) DVD burner connected to my Debian box.
Burning with kernel 2.4.27 and k3b works fine (no scrappy disks).
For some reason it does not work well with my kernel 2.6.7.
I've had some misburned DVD so far.
This is what my syslog says when I connect the drive:
Sep 11 10:27:19 localhost kernel: ieee1394: Error parsing configrom for

Sometimes I get this when I insert a blank DVD-R:
error for blocks 0-15 ...

Sep 11 10:45:57 localhost kernel: isofs_fill_super: bread failed, dev=sr0,
iso_blknum=16, block=16
And when I start burning wit k3b I'll get this:
Sep 11 10:53:31 localhost kernel: Device sr0 not ready.
Sep 11 10:53:51 localhost last message repeated 173 times
Sometimes k3b doesn't get the job done and locks. Sometimes it works but
in half speed only (2x instead of 4x).
Is it possible that the kernel firewire module can't set the DMA mode for
the drive ?
I've read somewhere that the new firewire over ethernet module can cause
some trouble, so I excluded it from my kernel (I don't need that anyway).
Here is my kernel config for firewire:
#
# IEEE 1394 (FireWire) support
#
CONFIG_IEEE1394=m
#
# Subsystem Options
#
# CONFIG_IEEE1394_VERBOSEDEBUG is not set
# CONFIG_IEEE1394_OUI_DB is not set
CONFIG_IEEE1394_EXTRA_CONFIG_ROMS=y
# CONFIG_IEEE1394_CONFIG_ROM_IP1394 is not set
#
# Device Drivers
#
# CONFIG_IEEE1394_PCILYNX is not set
CONFIG_IEEE1394_OHCI1394=m
#
# Protocol Drivers
#
CONFIG_IEEE1394_VIDEO1394=m
CONFIG_IEEE1394_SBP2=m
# CONFIG_IEEE1394_SBP2_PHYS_DMA is not set
# CONFIG_IEEE1394_ETH1394 is not set
CONFIG_IEEE1394_DV1394=m
CONFIG_IEEE1394_RAWIO=m
CONFIG_IEEE1394_CMP=m
CONFIG_IEEE1394_AMDTP=m
Any suggestion ?
Thx for your help, Rado
